Is there a restaurant/bar connected to the concert hall where they allow patrons to enter concert before general public?

There is a bar in the same strip mall area you can go to. It's pretty nice

No

There is a bar inside, but no food. And no it is not open before the general public. There is a bar and grill at the Barrel House in the same shopping center.

Nope

No. Only early access is vip

no connected restaurant. Maybe if you have VIP access you can get in early (?)
